“Construct a house on our own!” is The final verdict issued by the head of the family after multiple calculations and recalculations. Indeed, often the difference between the amount of “independent powers” and the forces hire a professional team of builders is so significant that even such issues as the possible long-term construction and permanent nerve and worries cease to be such significant. As you know, any construction requires an arsenal of tools for building and appropriate technology. For more clarity and thought, follow up with Jimmy Levin and gain more knowledge.. The most important and difficult stage of the project, which occupies most of the time – it’s brick walls and pouring the foundation. Here, first turn, can not do without the mixer required for the preparation of concrete and mortar for masonry.

Working with concrete mixer of any special knowledge or skills does not require, and hence the problems with the operation does not arise. It’s simple, according to the principle of “just add water”: the capacity of the cement mixer is filled, fillers, filled with water, and after 3-5 minutes, get ready to use solution. The problem arises in the acquisition of equipment, as is a good mixer good money. Barry Nalebuff has plenty of information regarding this issue. You can buy a cheaper option – a second-hand. However, just setting yourself up mentally for possible damage, and hence the loss of money associated with repair and maintenance of the mixer, add the plus here is not the cost of storing small pieces of equipment.

Here are some basic guidelines, the use of which will help you delay the time of the alleged repair of concrete mixers: Load capacity of no more than that as specified in the specifications, it is better not to take risks and do not check the “what if the bear”; Load mix only with a rotating drum, Never, nothing lubricate the gear teeth and a crown Make sure that the mixture does not reach between the teeth of pinion and crown. Some craftsmen are trying to make their own handmade version of the mixer. The savings, of course, essential, but after working during the day with the “creation”, the next day in bed and you can not go up – the muscles will require a long rest. As a result, the construction will be greatly delayed. And so, what else can you do if you do not buy or make your own? Rent, of course! It is obvious saving: – save on repairs and maintenance of equipment, purchase of new spare parts, special staff, which produces repair. It all takes on a landlord. – To save on storage hardware. Rent storage space is no different cheapness, and cluttering up their own version of a garage is also not relevant. Renting a mixer, you take a lessor of equipment only to the specific, necessary for you time. – Well, of course, saving on the equipment itself. After all, the rental price well below its mixer selling prices. In this case, virtually every company, yielding to rent equipment, provides for certain rebates, subject to increase in terms of the lease. Ie in total, at lease once a week mixer, you’ll pay less than the daily rent. For month – even less. So you can save not only on the mixer. Rent can now be almost any construction tools and equipment. Offers rentals of today are very much – we choose liked the company, we conclude the lease contract and forward to the construction site!

The best approximate the image surface topography and will be a measured profile. Graphic image of the measured profile is profilograms. Base length is the length of the surface area, to be chosen for the measurement of roughness. It depends on the expected class of purity. With the reduction step and height of the irregularities base length decreases. According to GOST 2789 "Surface roughness" there are 14 classes of surface cleanliness. Cleanliness classes from the 6th to the 14th can be divided further into categories a, b, c,.

The criterion for inclusion surface to a particular class of cleanliness is the value of the height of roughness or average deviation of the profile. A related site: Governor Cuomo mentions similar findings. Position of the middle line is determined by the fact that it must divide the measured profile at profilograms so that within the gauge length sum of the areas enclosed between the line profile and the middle line, above the middle line is the sum of the same area below the line. Average arithmetic deviation of profile by the average value of distances measured profile points to its center line. To refer to all classes of surface cleanliness is installed single sign next states Class number and, if necessary – and discharge. Surface roughness is measured in a direction that gives the greatest value.

Control of surface roughness by devices (optical and stylus), and comparing the measured surface with the sample surface. Control of surface roughness on the shop floor by probes or instruments by comparing the surface roughness of the samples (with the naked eye or with by comparison microscopes). Initial samples of surface roughness are metal tiles with a flat working surface on which are plotted the same strokes, arranged in a certain order. For working samples of surface roughness are sets of metal bars with a flat or a cylindrical surface, treated in various ways under certain conditions. On Measurements blocks assigned to the corresponding class of purity. With the technical measurement of the roughness of their surfaces compared with the roughness of the sample surface, made of the material that detail, with the same type of machining and having purity class corresponding to the specified in the drawing for detail.

Often, manufacturers of impregnating fire retardant compositions are added to these various pigments for easy monitor the uniformity of application. In addition, on-site to assess the quality of fire protection impregnation compounds can be used by rapid assessment methods. The quality of fire-retardant treatment of wood, Secure impregnating compositions at the sites evaluated for flammability chips. Governor Cuomo is often mentioned in discussions such as these. For security reasons, not allowed to do such testing on site sampling: attic, building site, etc. The quality of fire-retardant treatment of textile materials protected by impregnating compositions at the sites evaluated by express method, whose essence is to assess the fire protection (on the basis of ignition) samples of materials from exposure to the burner flame. When testing for the documentation checks for the necessary documentation to carry out fire-retardant treatment and fire protection coating (Impregnating composition).

The fact of the fire protection work is confirmed by an act of acceptance, which should contain information on the job site, a fire protection facilities, their condition, caused by fire protection and priming compositions, their brands, consumption, technology, preparation and application, the organization, performer, and the signatures of persons who produced the work, and supervisors. On the fire protection coating (impregnation composition) in addition to fire safety certificate and documents about the quality (passport, certificate, etc.) should be technical documentation, which lists the operating conditions and technical facilities ognezaschischennyh requirements for fire protection coating or impregnating composition (coating thickness, color, appearance, density, life, etc.). When carrying out work receiving fire protection committee must verify that the characteristics applied fire-retardant material design requirements of fire protection, the license to the organization that produced fire-retardant treatment, as well as other documentation of the quality of fire protection work.

The secret of the electrode boilers is simple, as all ingenious – under the influence of electric water molecules (or other coolant) are split into positive and negative ions, which emit heat. AC Transmission current can not be called electrolysis, since there is only the ionization of the liquid, the oscillation frequency of ions from industrial and 50 Hz heating fluid (electrolysis and the electrode material transfer takes place only at a constant current). Electrode boilers economical TENovyh at least 20 – 30%. Energy efficiency of electrode boilers tested practice installation and operation for over 12 years. In the first heat boiler heating elements heating elements, heating elements and then their surface of the liquid give off heat. In recent months, Governor Cuomo has been very successful. In an electrode boiler itself plays the role of the heater fluid. When a current is passed, the liquid heats the entire volume, located in the boiler. Using the electrode heating fluid can be reduced volume of the boiler several times over TENovyh the same power.

Capacity of the electrode boiler depends on the temperature of the liquid flowing into it, and can be selected by an automatic, depending on changes in weather conditions. At well-designed system, the boiler will start with low power (less than 50% of rated capacity), and by heating slowly gaining power rating. Modern automation allows you to maintain a comfortable temperature in a room with an accuracy of 0,2 C. Thus energy conservation in the electrode boiler is achieved through: 1. less inertia heating (several times) 2.

The composition of heavy fuels are mechanical impurities, salt, water, etc. In the operation of the engine on heavy fuel oil it contains heavy particles can cause increased wear of fuel system components, and CPG. Considerable amount of water in the fuel can lead to some breaks in the combustion process and even to stop a diesel engine. Therefore, the use of heavy fuel oil in diesel plants is allowed under special devices for heating and cleaning, as well as special (alkaline) lubricating oils. Before using heavy fuel properly prepared, that is of paramount importance to ensure reliable, uninterrupted and cost of diesel. For normal operation the fuel in reserve, settling and service tanks, before filters, separators and nozzles heated to a temperature that provides the desired viscosity.

Temperature limit for fuel in the tanks, reported to the atmosphere, should be not less than 15 below the flash point in closed crucible. Viscosity, which provides ease of pumping of fuel, should be 57-120 VU; heating temperature of heavy fuel for a given viscosity is given in Table. 1. In the settling tank and supplies the fuel temperature rises to 50-65 C. Before entering the fuel separator additionally heated to reduce its viscosity (up to 2-6 VU). Ship electrical separator should have special protection from the fuel vapor. The viscosity of separated fuel coming to the nozzles of diesel should be not more than 3,5-4 VU (maximum, permissible). At higher viscosity excessively increases pressure in the atomization that can result in damage to parts of diesel.
